Mini-Contests? Sign me up!

My, my, the changes that have taken place since I've been away....

Some sad, like Katie Leone's sudden passing (and more on that after I've had a little sleep--RIP Katie) and some pleasantly surprising, like these "mini-contests."

Where are the rules for each month's contest posted? I've looked in the usual section for contests, but have found nothing. I doubt I'll be able to contribute anything for this month, but May is a possibility.
